ZF2 navigation translate navigation labels and titles

Question

I'm trying to find a way to translate the labels and titles. According to he ZF2 Manual all I have to do this:

The navigation helpers support translation of page labels and titles. You can set a translator of type Zend\\I18n\\Translator in the helper using $helper->setTranslator($translator).

So my navigation looks like this in config file

return array(
    'navigation' => array(
        'default' => array(
            array(
                'label' => 'Home',
                'route' => 'home',
            ),
            array(
                'label' => 'Users',
                'route' => 'tar-users',
            ),
        ),
    ),
);

This is in global.php

return array(
    'service_manager' => array(
        'factories' => array(
            'navigation' => 'Zend\Navigation\Service\DefaultNavigationFactory',
        ),
    ),

    //...
);

And in my layout I have:

<?php echo $this->navigation('navigation')
        ->setTranslator($this->plugin('translate')->getTranslator())
        ->menu()
        ->setUlClass('nav navbar-nav')
        ->setMaxDepth(0)
    ?>

The navigation is working but is not translating. I'm sure I missed something or I did something wrong. I'd like to know what. I don't what you to write the code just some tips.

Thank you.

Zend uses .po files in Application/language folder, and you need to use poedit to edit gettext translations. Poedit scans the . php ( or .phtml files in this case ) for phrases to translate, more precisely, seeks for the translate function name ( translate in this case ). Check HERE how to configure poedit for Zend, and HERE is simple solution for translating menu labels. I have just started learning Zend, i'm not sure if this is the right approach, but it is the simplest solution that I encountered. You just need to add label values as $translator->translate( ... ) in Application/config/module.config.php , an configure translator ( in skeleton application, en_US locale, and gettext type ). After that open .po file and refresh catalog, new lines should be added for translation ( also, you can't, and should not add new translations that are not found automatically by the program ). I have tested the above, and menu is translated automatically without setTranslator( ... ) call.

do you setup the translator service and locale in your module.config.php? something like this:

'translator' => array(
    'locale' => 'it_IT',
    'translation_files' => array(
        array(
            'type'     => 'phpArray',
            'filename' => __DIR__ . '/../language/Zend_Captcha.php',
            'text_domain' => 'default'
        ),
        array(
            'type'     => 'phpArray',
            'filename' => __DIR__ . '/../language/Zend_Validate.php',
            'text_domain' => 'default'
        ),
    ),
    'translation_file_patterns' => array(
        array(
            'type'     => 'gettext',
            'base_dir' => __DIR__ . '/../language',
            'pattern'  => '%s.mo',
        ),
    ),
),

I've run into a puzzling circumstance where I had also set everything up correctly, but the translation wouldn't execute...because the proper locale wasn't installed on the OS. I was trying to translate en_US into fr_CA. This quickly fixed things for me:

sudo locale-gen fr_CA sudo locale-gen fr_CA.UTF-8

Answer 4

I had the same problem, and here is my solution. (Using gettext )

Example:

module.config.php

array (
    'label' => _('Home'),
    'route' => 'home'
),

In the View, you will use something like this:

$this->translate(HERE_COMES_THE_ITENS_OF_NAVIGATION)

In my case I use this:

foreach ( $this->container as $page ) {
   $this->translate($page->getlabel ());
}

In the POEDIT program, you will insert two sources keywords

1 - translate
2 - _

The "_" is to map the keyword by POEDIT, and ZEND uses the "translate" to replace it by the value you put inside the POEDIT.

Zend comes with translation on navigation but not before rendering. This snippet will do the trick. (Zend 3)

$sm = $event->getApplication()->getServiceManager();
$vhm = $sm->get('ViewHelperManager');
$translator = $sm->get('translator');
$vhm->get('navigation')->setTranslator($translator);

Review the script in your module.config.php

// module.config.php
fufunction _(string $msg){return $msg}

function _(string $msg){return $msg}

return array(
    'navigation' => array(
        'default' => array(
            array(
                'label' => _('Home'),
                'route' => 'home',
            ),
            array(
                'label' => _('Users'),
                'route' => 'tar-users',
            ),
        ),
    ),
    'view_helpers' => [
        'aliases' => [
            '_'                 => Translate::class,
            'numberFormat'      => NumberFormat::class,
            'formLabel'         => FormLabel::class,
            'formSubmit'        => FormSubmit::class,
            'menu'              => Navigation::class,
        ],

        'factories' => [

            Translate::class => function($container) {
                $instance = new Translate();
                $instance->setTranslator($container->get(Translator::class));
                return $instance;
            },

            FormLabel::class => function($container) {
                $instance = new FormLabel();
                $instance->setTranslator($container->get(Translator::class));
                return $instance;
            },

            FormSubmit::class => function($container) {
                $instance = new FormSubmit();
                $instance->setTranslator($container->get(Translator::class));
                return $instance;
            },

            Navigation::class => function($container) {
                $instance = new Navigation();
                $instance->setTranslator($container->get(Translator::class));
                $instance->setServiceLocator($container);
                return $instance;
            },
        ]
);
